I was looking through the
list of UNESCO World Heritage Sites and noticed that all the ones listed as threatened are in places you might expect (Afghanistan, Africa, Iraq) except for 3. Everglades National Park, Liverpool* and Vienna are the only sites in first world countries that are threatened. There is already a foundation dedicated to saving the Everglades, so we need to start a foundation dedicated to saving Vienna.
I suggest the entire world starts sending spent nuclear reactor fuel to a depot right in the Belvedere palace. That should save Vienna.
* I don't really care about Liverpool, because
